Will charging with a high-power charger damage your phone's battery? Learn the important facts.

Many people fear that charging with a high-power charger will damage your phone. If you share this concern, we've come up with the answer.

Sometimes, in an emergency, you have to charge your phone with a different charger. This raises the question: will charging with a high-power charger damage your phone? If this question bothers you too, we've come up with the answer today. This will help you determine whether a low-capacity phone will be damaged if charged with a high-power charger.

Charging with a high-power charger is safe

If your phone is 18W and you charge it with an 80W or 100W charger, there's no need to worry. It's completely safe and won't harm your phone or battery. Chargers and smartphones use a technology called the Power Negotiation Protocol. This technology ensures that the phone receives power appropriate to its capacity. So, even if you use a higher-powered charger, the phone will still receive charging appropriate to its capacity.

How This Technology Works

The Power Negotiation Protocol tells the charger the phone's capacity and how much power it will need to charge. The charger then delivers only that much power. For example, an 18W phone will only receive 18W of power even from a 100W charger. This protects the phone and battery.

A Battery Management System Also Helps

Modern smartphones also include a battery management system. It manages charging voltage, temperature, and current using the Power Negotiation Protocol. If the phone overheats during charging, it stops charging, protecting the battery.
